Here is a different current sensor

This one gives the following data and values, seems to work on a different formula?

$7F $9E = 2A
$7C $9C = 8A
$78 $9B = 16A
$83 $9F = -6A

Looks like anything over $7F in first byte is a negative value


And one more this is reporting voltage.

$98 $B1 = 158V
$9B $99 = 162V
$9C $80 = 163V

Seems to be just the first byte involved + 6?
